Over 70 equations approximating thermodynamic and transport properties of water and steam at pressure 1 bar and saturated pressure as well as air at pressure 1 bar were tested against reference data. Their accuracy and relative computing time were reported.
OBJECTIVES: To standardise the colorimetric assay based on 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) for the rapid detection of rifampicin-resistant Mycobacterium tuberculosis in clinical practice and to evaluate the assay on a collection of 92 clinical isolates. DESIGN: The Bactec method was used as the reference method. Rifampicin was used for the susceptibility testing
We used roentgen stereophotogrammetric analysis to follow 33 C-stem femoral components for two years after primary total hip arthroplasty. All components migrated distally and posteriorly within the cement mantle. The mean distal migration was 1.35 mm (SD 0.62) at two years and the mean posterior migration was 1.35 mm (SD 0.69) at two years. All the femoral components rotated into retroversion wit
Ion microprobe U-Th-Pb analyses of zircons in variably metamorphosed and veined orthogneisses in the southern part of the parautochthonous Eastern Segment of the Sveconorwegian (1.20-0.90 Ga) orogen, SW Sweden, broadly define two age groups, oscillatory and sector zoned magmatic zircon cores yield 1.70-1.68 Ga while overgrowths, homogeneous crystals, and recrystallized domains in primary zircon yi
OBJECTIVES: The aim of this study was to identify clinical characteristics of depression in elderly people that could be useful for case finding in general practice. DESIGN: A cross-sectional study of clinical characteristics through review of medical records. SETTING: Herrhagen health centre, Karlstad, Sweden. SUBJECTS: Seventy-one persons with a high depressive score in a screening of depressive
The Bacillus subtilis aprE leader is a determinant of extreme mRNA stability. The authors examined what properties of the aprE leader confer stability on an mRNA. The secondary structure of the aprE leader mRNA was analysed in vitro and in vivo, and mutations were introduced into different domains of an aprE leader-lacZ fusion. The half-lives of the corresponding transcripts were determined and be
Reaction of the tetradentate ligand N-(2-hydroxybenzyl)-N, N-bis(2-pyridylmethyl) amine (L - OH) with MoO2Cl2 in methanol in the presence of NaOMe and PF6- results in the formation of [MoO2(L - O)] PF6. Similarly, the reaction of N-(2-mercaptobenzyl)- N,N-bis(2-pyridylmethyl) amine (L -SH) with MoO2(acac)(2) leads to the formation of [MoO2(L - S)](+). The dioxo-molybdenum complex [MoO2(L - O)](+)
In this article I present findings from my earlier research on reconciliation in South Africa and Northern Ireland, together with some issues raised by my current research project on “reconciliation in South Africa from women’s perspectives”. Reconciliation is seen as a process whereby the diverse “moral landscapes” held in a war-torn society are addressed, with the aim of building, rebuilding or
The aim of this qualitative study was to explore older persons' (n = 28, 75-96 years of age) experience of becoming in need of public home help, their experience of participation and of having influence on the needs assessment procedure and the decisions made about public home help. A content analysis revealed a broad overarching category, labelled: experiencing discontinuity in life as a whole -
Gene expression for glial cell line-derived neurotrophic factor (GDNF) family ligands and receptors was analyzed with in situ hybridization after two focal ischemic insults of different severities. Focal ischemia was induced in rats by either 30 min or 2 h of middle cerebral artery occlusion (MCAO), causing damage to the striatum only, or involving also the parietal cortex, respectively. We found
OBJECTIVES: To identify risk factors of carcinoma of the extrahepatic biliary tract in men. METHODS: Newly diagnosed and histologically confirmed patients, 35-70 years old, were interviewed between 1995 and 1997 in Denmark, Sweden, France, Germany and Italy. Population controls were frequency-matched by age and region. Adjusted odds ratios and 95%-confidence intervals were estimated by logistic re
This article explores to what extent married middle-aged individuals in Europe are governed by the risk of experiencing divorce, when shaping their physical appearance. The main result is that divorce risks, proxied by national divorce rates, are negatively connected to body mass index (BMI) among married individuals but unrelated to BMI among singles. Hence, it seems that married people in societ
The neurohypophysial peptide arginine vasotocin, and its mammalian ortholog arginine vasopressin, influence a wide range of physiological and behavioral responses, including aspects of sexual and social behaviors, osmoregulation, stress response, metabolism, blood pressure, and circadian rhythms. Here, we demonstrate that, in zebrafish (Danio rerio), the vasotocin precursor gene arginine vasotocin
The aerosol in the Amazon basin is dominated throughout the year by organic matter, for the most part soluble in water. In this modeling study, we show how the knowledge of water-soluble organic compounds (WSOC) and the associated physical and chemical properties (e.g. solubility, surface tension, dissociation into ions) affect the hygroscopic growth and activation of the aerosol in this area. The
The monoclonal gammopathies are a group of disorders associated with monoclonal proliferation of plasma cells. The characterization of specific entities is an area of difficulty in clinical practice. The International Myeloma Working Group has reviewed the criteria for diagnosis and classification with the aim of producing simple, easily used definitions based on routinely available investigations
Mice were subjected to gastrectomy (GX) or sham operation (controls). Four to six weeks later the pancreatic islets were isolated and analysed for cAMP or alternatively incubated in a Krebs-Ringer based medium in an effort to study insulin secretion and cAMP accumulation in response to glucose or the adenylate cyclase activator forskolin. Freshly isolated islets from GX mice had higher cAMP conten
Background: The identification of novel genes by high-throughput studies of complex diseases is complicated by the large number of potential genes. However, since disease-associated genes tend to interact, one solution is to arrange them in modules based on co-expression data and known gene interactions. The hypothesis of this study was that such a module could be a) found and validated in allergi
